Holy Sheet!

Holy Sheet originated as an inside joke that Miggeh at said at one point during a conversation with Emerald.Emerald, thinking it was quite funny at the time, created a little icon to go along with it. It later was added as a badge on the forum as of April 5th, 2011. Its criteria are unknown, and the two staff members seem to want to keep it that way.
